Just got back trail camera pics from my Wisconsin farm from the last month and I had 3 pics of 2 different deer with 1/2 of their racks from last fall. The pictures were from March 28th and April 6th. One was just a spike but the other was a decent 2 1/2 year old deer. The rack was broken half way up the main beam. My question was if this is common and how it effects the 2010 antler growth when some of the other deer are starting to show growth for 2010. Thanks Luke
